United States, residinglat jHnustomfinthe countyV of- Harris and State f of "Texas, have invented' certain new and useful' Improve- Inentsin VireForining Machines, o which I p the following is 'aspecieation This inventionrelates to v improvements Y in a wire forming rnaohine and has particular relation to a maoh-lneof Vthe Character describedv by whichwlre 1s formed into Clothes pins, vand, this applicaa' -tion has been yfiledas `asubstitute lifo'rour orignalfapplioation' filed onl July 30, 1917, Serial-No, 183,476.- v L The object of the -inventioni's to provide l a.dev ce` of vthe oharaeterfdeseribedainto' which wirefisfed andv whereby said'wirelis* lautomaticallyiiorined intoclothesfpins. i Another feature of theinvention-.resides `in the provision jof means-for kforming a split ring `and attaching,k the p'invthereto,

said ring being provided `for the purpose of suspending the pin from the clothesline.

A `further feature of vthe device resides `in the provision `of means for feeding the wireinto the-machine-- -v .l l,

The plate 108 is/detachably secured to the free end :of-the arm 10,9,whch is fixed to one Vend of thesleeve 101; To the other end of this sleeve the lever 110 is fixed. VThe free end of this lever hasa roller bearing 111, which is held in contact with the cam V112, fixed upon the camshaft 7, vby thepull spring 113,one end of which is attached to said lever 110,'and the other end of which is The cam 112, is formed to oscillate the sleeve101, so asfto withdraw the guide plate fromthe face of the bearing 63, during the movement of the wire feed mechanism to permit the passage of the needle, andV upon the withdrawal of the needle it operates to clamp said plate against the wire to hold the wire in place `during the formation of the pin. The plate Y.

These cams operate through said levers to partially vrotate the shaft 114, and sleeve 117, respectively, and oscillate the arms 116, and 118, `back and forth to project and Vwithdraw vthe corre sponding pins 76, 81, `66 and 62, at the "proper time as hereinbefore stated.

Theshaft 115 is rotatable in suitable bearings and provided 'with the slee-ve 123. Fixed to the shaft 1151 is the arm 124, whose yfree end operates'inva notch in thefunder side of the yoke 125, :carried by the inner end of ther-pin, 91,an'd the sleeve'123, has an arm -126"fixedjthereto whose free end operatesfin a notch inf the under side'of the yoke 127, "carried'by' the inner end of the pin 84.

. Rotatably'mounted in suitable bearings carriedbythe end of the framework is the 'countershaft 136, the inner end `of which .has the fixed bevel pinion 137`arranged to mesh with the gear sector l138, carried by the'band wheel 41, which imparts intermit-V t 'tenti rotations thereto. Fixed upon this shaft 136, is the lock shoef139, having a flat i face Vwhich bears against the `opposing edge of said band wheel 4 1, tolock the countershaft against rotation when vthe pinion 137,

is not in mesh with said sector 138, a section of said rim opposite said sector being cut away at 140, to permitthe lockV shoe and shaft to rotate. I The outer end of said shaft has .the fixedmiter gear 141,v which isfin meshl with a'corresponding Vmiter'gear 142,
